Hardy Ornamental Flowering Trees and Shrubs Part 7

DAPHNIPHYLLUM.

DAPHNIPHYLLUM GLAUCESCENS.--East Indies, Java and Corea. A handsome j.a.panese shrub that will be valued for its neat Rhododendron-like foliage, compact habit of growth, and for the conspicuous bark which is of a warm reddish hue. The leaves are large and elliptic, six inches long, and are rendered strangely conspicuous from the foot-stalks and midrib being dull crimson, this affording a striking contrast to the delicate green of the leaves. It grows freely in light sandy peat.

There are two well-marked forms, one named D. glaucescens viridis, in which the red markings of the leaves are absent; and D. glaucescens jezoensis, a pretty and uncommon variety.

DESFONTAINEA.

DESFONTAINEA SPINOSA.--Andes from Chili to New Grenada, 1853. This is a desirable shrub, and one that is perfectly hardy in most parts of the country. It is a charming shrub of bold, bushy habit, with p.r.i.c.kly holly-like foliage, and scarlet and yellow, trumpet-shaped pendent flowers, borne in quant.i.ty. The shelter of a wall favours the growth and flowering of this handsome shrub, but it also succeeds well in the open if planted in rich, light soil, and in positions that are not exposed to cold and cutting winds.

DEUTZIA.

DEUTZIA CRENATA (_syn D. scabra_ and _D. Fortunei_).--j.a.pan 1863. This is of stout, bushy growth, often reaching a height of 8 feet, and lateral spread of nearly as much. The ovate-lanceolate leaves are rough to the touch, and its slender, but wiry stems, are wreathed for a considerable distance along with racemes of pure white flowers. It is a very distinct shrub, of n.o.ble port, and when in full flower is certainly one of the most ornamental of hardy shrubs. The double-flowered form, D. crenata flore-pleno, is one of the prettiest flowering shrubs in cultivation, the wealth of double flowers, not white as in the species, but tinged with reddish-purple being highly attractive. D. crenata, Pride of Rochester, is another form with double-white flowers, and a most distinct and beautiful shrub. Two other very beautiful varieties are those known as D. crenata Watererii and D. crenata Wellsii.

D. GRACILIS is a somewhat tender shrub of fully 18 inches high, with smooth leaves and pure-white flowers produced in the greatest freedom.

It does well in warm, sheltered sites, but is most frequently seen as a greenhouse plant. A native of j.a.pan.

DIERVILLA.

DIERVILLA FLORIBUNDA (_syn D. multiflora_ and _Weigelia floribunda_), from j.a.pan, 1864, has narrow, tubular, purplish-coloured corollas, that are only slightly opened out at the mouth. The Diervillas are valuable decorative shrubs, of free growth in good rich loam, and bearing a great abundance of the showiest of flowers. For shrubbery planting they must ever rank high, the beautiful flowers and rich green ample leaf.a.ge rendering them distinct and attractive.

D. GRANDIFLORA (_syn D. amabilis_ and _Weigelia amabilis_).--j.a.pan.

This is of larger growth than D. rosea, with strongly reticulated leaves, that are prominently veined on the under sides, and much larger, almost white flowers. It is a distinct and worthy species.

There are some beautiful varieties of this species, named Isolinae, Van Houttei, and Striata.

D. ROSEA (_syn Weigelia rosea_).--China, 1844. This is a handsome hardy shrub of small stature, with ovate-lanceolate leaves, and cl.u.s.ters of showy pink, or sometimes white flowers, that are produced in April and May. There are many good varieties of this shrub, of which the following are the most popular:--D. rosea arborescens grandiflora; D.

rosea Lavallii, with an abundance of crimson-red flowers; D. rosea Stelzneri, with an abundance of deep red flowers; D. rosea hortensis nivea, large foliage, and large, pure-white flowers; D. rosea candida, much like the latter, but bearing pure-white flowers; and D. rosea Looymansii aurea has beautiful golden leaves.

DISCARIA.

DISCARIA LONGISPINA.--This is at once a curious and beautiful shrub, of low, creeping growth, and poorly furnished with leaves, which, however, are amply made up for by the deep green of the shoots and stems, and which give to the plant almost the appearance of an evergreen. The flowers, which are bell-shaped and white, are almost lavishly produced, and as they last for a very long time, with only the pure white a.s.suming a pinky tinge when subjected to excessive suns.h.i.+ne, the value of the shrub is still further enhanced. For planting against a mound of rock this scrambling shrub is of value, but the position should not be exposed to cold winds, for the plant is somewhat tender. From South America, and allied to the better known Colletias.

D. SERRATIFOLIA (_syn Colletia serratifolia_), is even a handsomer plant than the former, with minute serrated foliage, and sheets of small white flowers in June.

DIOSPYROS.

DIOSPYROS KAKI COSTATA.--The Date Plum. China, 1789. Fruit as big as a small apple; leaves leathery, entire, and broadly ovate; flowers and fruits in this country when afforded the protection of a wall. The fruit is superior to that of D. virginiana (Persimmon).

D. LOTUS, the common Date Plum, is a European species, with purplish flowers, and oblong leaves that are reddish on the under sides. Both species want a light, warm soil, and sheltered situation.

D. VIRGINIANA.--The Persimmon, or Virginian Date Plum. North America, 1629. A small-growing tree, with coriaceous leaves, and greenish-yellow flowers. In southern situations and by the seaside it is perfectly hardy, and succeeds well, but in other districts it is rather tender.

The fruit is edible, yellow in colour, and about an inch in diameter.

DIRCA.

DIRCA PAl.u.s.tRIS.--Leather Wood. North America, 1750. A much-branched bush, of quite a tree-like character, but rarely more than 3 feet high.

To the Daphnes it is nearly allied, and is close in resemblance; but there is a curious yellowish hue pervading the whole plant. The flowers are produced on the naked shoots in April, and are rendered conspicuous by reason of the pendent yellow stamens. They are borne in terminal cl.u.s.ters of three or four together. It delights to grow in a cool, moist soil, indeed it is only when so situated that the Leather Wood can be seen in a really thriving condition.

DRIMYS.

DRIMYS AROMATICA (_syn Tasmannia aromatica_).--Tasmanian Pepper Plant.

Tasmania, 1843. This is, if we might say so, a more refined plant than D. Winteri, with smaller and narrower leaves, and smaller flowers. The plant, too, has altogether a faint reddish tinge, and is of upright growth. A native of Tasmania, and called by the natives the Pepper Plant, the fruit being used as a subst.i.tute for that condiment. Like the other species the present plant is only hardy in warm, maritime places, and when afforded the protection of a wall.

D. WINTERI (_syn Winter a aromatica_).--Winter's Bark. South America, 1827. The fine evergreen character is the chief attraction of this American shrub, so far at least as garden ornamentation is concerned.

With some persons even the greenish-white flowers are held in esteem, and it cannot be denied that a well flowered plant has its own attractions. The long, narrow leaves are pale green above and glaucous beneath, and make the shrub of interest, both on account of their evergreen nature and brightness of tint. Unfortunately it is not very hardy, requiring even in southern England a sunny wall to do it justice.

ELAEAGNUS.

ELAEAGNUS ARGENTEA.--Silver Berry. North America, 1813. A spreading shrub 8 feet or 10 feet high, with lanceolate leaves clothed with silvery scales. The flowers are axillary and cl.u.s.tered, and are succeeded by pretty, silvery-ribbed berries.

E. GLABRA (_syn E. reflexus_).--From j.a.pan. This is one of the handsomest species, forming bushes of delightful green, leathery leaves, and with a neat and rather compact habit of growth. It grows with great freedom when planted in light, sandy soil, big globose bushes being the result of a few years' growth. Being perfectly hardy it is to be recommended if only for the ample leathery, deep green foliage. The flowers are inconspicuous. There is a form having the leaves margined with pale yellow, and known under the name of E. glabra variegata.

E. LONGIPES (_syn E. edulis_ and _E. crisp a_).--j.a.pan, 1873. This species, is also worthy of culture, whether for the ornamental flowers or fruit. It is a shrub 6 feet high, bearing an abundance of spotted, oval red berries on long footstalks. Quite hardy.

E. MACROPHYLLA.--j.a.pan. This is of robust growth, with handsome, dark green leaves, and purplish branch tips. The leaves are thick of texture, often fully 3 inches long, glossy-green above, and silvery beneath. The latter is all the more remarkable, as the leaves have the habit of curling up their edges, and thus revealing the light, silvery tint of the under sides. It thrives well in light, sandy peat, and may be relied upon as one of the hardiest of shrubs.

E. ROTUNDIFOLIA.--An interesting and perfectly hardy species, growing about five feet high, and remarkable for the great wealth of pretty scarlet and amber-coloured berries. The flowers are not very showy, but this is made up by the beautiful silvery leaves, most p.r.o.nounced on the under sides, and wealth of fruit, which hangs on long stalks like Cherries.

Other species of less interest are E. pungens, of which there is a variegated variety; E. Simoni, a neat Chinese shrub; and E. latifolia, of good habit and with large leaves. The various species and varieties of Elaeagnus may all be cultivated in light, free soil, and from experiments that were recently made, they have been found of great value for planting by the seaside. They are popularly known as the Wild Olives and Evergreen Oleasters.

EMBOTHRIUM.

EMBOTHRIUM COCCINEUM.--Fire Bush. South America, 1851. This is a beautiful shrub, of tall growth, with flowers of great interest and beauty. Except in warm and favoured situations, it is not very hardy, and should always be grown as a wall plant. The fiery scarlet, orange-tinted flowers, resembling somewhat those of the Honeysuckle, are very beautiful by the first weeks of May. It grows to about 6 feet in height in southern England, and is, when in full flower, a shrub of unusual beauty.

EPHEDRA.

EPHEDRA VULGARIS (_syn Ephedra monastachya_), from Siberia, 1772, is a half-hardy shrub of trailing habit, with inconspicuous flowers.

Thriving in very poor soil, or on rocky situations, is the only reason why it is introduced here.

EPIGAEA.

EPIGAEA REPENS.--Ground Laurel, or New England Mayflower. Northern United States, 1736. This is, perhaps, in so far as stature is concerned, hardly worthy of a place in our list, yet it is such a pretty and useful shrub, though rarely rising more than 6 inches from the ground, that we cannot well pa.s.s it over. For planting beneath Pine or other trees, where it can spread about at will, this prostrate shrub is most at home. There it enlivens the spot with its pretty evergreen foliage, and sweet-scented, white or pinky flowers. It is quite hardy.

ERCILLA.

ERCILLA SPICATA (_syn Bridgesia spicata_).--Chili, 1840. A small-growing, half-climbing shrub, with leathery, deep green leaves, and inconspicuous flowers. Hailing from Chili, it is not very hardy, but given the protection of a wall, or planted against a tree-stump, it soon forms a neat ma.s.s of evergreen foliage.
